If I just install this mild upgrade, should I have to mess with rejetting all over again?

What kind of power increase will I see and how difficult is it to install?

Also, will I need anything else to go along with these?


Thanks

 

If you're just going with the Stage 1 you don't need the springs. It should give you a nice improvement in overall power. Not sure on the complexity of installation. Hope this helps a little. Good luck!

 

I would do the springs only for peace of mind [img]i/expressions/face-icon-small-wink.gif[/img]

I wouldn't put a cam in my own car without changing springs...it's just for insurance [img]i/expressions/face-icon-small-smile.gif[/img]

 

I have the 11:1 and Stage 1 Hotcam and have the stock springs. They may not last forever, but they are doing just great so far after about 4 months of hard riding! It's totally up to you whether you want to chance it. Hotcam says it is not necessary.

I have the stage1 hotcams with stock Valve springs, and they work great. The installation isn't hard, if you know how to do it. I didn't, so a few friends helped me, but now that I know what to do, I think I could do it by myself.

You may not be able to re-use the Raptor's decompression mechanism. do a search on that, there was just a big post over it.
